Coal briquette advantages during burning

Coal briquette machine is for pressing coal dust into different shapes of briquette.

Coal briquete have some advantages than lump coal during burning :

1. Because of the even size, there are gaps of the briquette coals when burning, which also lead to the uniform bed resistance in the gas furnace. This can improve the strength of airflow and help the full burning of the briquette coals.
2. The porosity of briquette coals is higher than that of lump coal, so it can increase the contact area of briquette coals and steam, thus to improve the intensity of gasification eventually. 
3. In the process of gasification, the briquette coal is good into slag and there is low carbon content in the slag. Especially when the gasifier uses special furnace to calculate and in the case of stable operation, the carbon content in the slag will be lower than that in the gasification of the lump coal.
4. Due to the porosity of briquette coals is higher than that of lump coal, so it can reduce the excess coefficient of the air in the furnace and decrease the resistance of bed ventilation, which helps to improve the blowing intensity and gasification strength in the gas furnace.
